This study evaluated the feasibility of using occipitoparietal alpha activity to drive target/non-target classification in a brain-computer interface for communication. EEG data were collected from 12 participants who completed BCI Rapid Serial Visual Presentation calibrations at two different presentation rates: 1 and 4 Hz. Attention-related changes in posterior alpha activity were compared to two event-related potentials : N200 and P300. Machine learning approaches evaluated target/non-target classification accuracy using alpha activity. Results indicated significant alpha attenuation following target letters at both 1 (...) and 4 Hz presentation rates, though this effect was significantly reduced in the 4 Hz condition. Target-related alpha attenuation was not correlated with coincident N200 or P300 target effects. Classification using posterior alpha activity was above chance and benefitted from individualized tuning procedures. These findings suggest that target-related posterior alpha attenuation is detectable in a BCI RSVP calibration and that this signal could be leveraged in machine learning algorithms used for RSVP or comparable attention-based BCI paradigms.

The speech-to-song illusion ( Deutsch et al., 2011 ) tracks the perceptual transformation from speech to song across repetitions of a brief spoken utterance. Because it involves no change in the stimulus itself, but a dramatic change in its perceived affiliation to speech or to music, it presents a unique opportunity to comparatively investigate the processing of language and music. In this study, native English-speaking participants were presented with brief spoken utterances that were subsequently repeated ten times. The utterances were (...) drawn either from languages that are relatively difficult for a native English speaker to pronounce, or languages that are relatively easy for a native English speaker to pronounce. Moreover, the repetition could occur at regular or irregular temporal intervals. Participants rated the utterances before and after the repetitions on a 5-point Likert-like scale ranging from “sounds exactly like speech” to “sounds exactly like singing.” The difference in ratings before and after was taken as a measure of the strength of the speech-to-song illusion in each case. The speech-to-song illusion occurred regardless of whether the repetitions were spaced at regular temporal intervals or not; however, it occurred more readily if the utterance was spoken in a language difficult for a native English speaker to pronounce. Speech circuitry seemed more liable to capture native and easy-to-pronounce languages, and more reluctant to relinquish them to perceived song across repetitions. (shrink)

Traditionally, Lucian’s Navigium is regarded as a moralizing dialogue, which criticizes unrealistic aspirations. Lycinus incorporates this criticism by attacking his friends ironically. This essay elaborates that the dialogue also offers a more ethical interpretation that problematizes Lycinus’ moralizing attitude towards his friends. It argues that Timolaus, one of Lycinus’ interlocutors and friends, introduces a discourse about the reciprocal connection between the act of storytelling on the one hand, and friendship on the other. By doing so, aesthetics (stories) and ethics (friendship) (...) appear as complementary. To emphasize this perspective on the dialogue, the modern concept of narrative communities is connected with ancient concepts of friendship. Lycinus’ ironizing voice and behavior can then be seen as antagonistic rather than dominant. Timolaus, however, appears as subtle narrator, who by his own wish tries to make Lycinus aware of the importance of storytelling for friendship. (shrink)

Genetic determinism can be described as the attribution of the formation of traits to genes, where genes are ascribed more causal power than what scientific consensus suggests. Belief in genetic determinism is an educational problem because it contradicts scientific knowledge, and is a societal problem because it has the potential to foster intolerant attitudes such as racism and prejudice against sexual orientation. In this article, we begin by investigating the very nature of belief in genetic determinism. Then, we investigate whether (...) knowledge of genetics and genomics is associated with beliefs in genetic determinism. Finally, we explore the extent to which social factors such as gender, education, and religiosity are associated with genetic determinism. Methodologically, we gathered and analyzed data on beliefs in genetic determinism, knowledge of genetics and genomics, and social variables using the “Public Understanding and Attitudes towards Genetics and Genomics” instrument. Our analyses of PUGGS responses from a sample of Brazilian university freshmen undergraduates indicated that belief in genetic determinism was best characterized as a construct built up by two dimensions or belief systems: beliefs concerning social traits and beliefs concerning biological traits; levels of belief in genetic determination of social traits were low, which contradicts prior work; associations between knowledge of genetics and genomics and levels of belief in genetic determinism were low; and social factors such as age and religiosity had stronger associations with beliefs in genetic determinism than knowledge. Although our study design precludes causal inferences, our results raise questions about whether enhancing genetic literacy will decrease or prevent beliefs in genetic determinism. (shrink)

Obtaining and sharing genetic information when there is a potential conflict of interest between patients and their relatives give rise to two questions. Do we have a duty to find out our genetic predispositions for disease for the sake of our relatives, or do we have a right to remain ignorant? Do we have a duty to disclose our known genetic predispositions for disease to our relatives? I argue that the answer to both questions is yes, but to a lesser (...) extent than sometimes claimed.

Niklas Luhmann is widely recognized as one of the most original thinkers in the social sciences today. This major new work further develops the theories of the author by offering a challenging analysis of the relationship between society and the environment. Luhmann extends the concept of "ecology" to refer to any analysis that looks at connections between social systems and the surrounding environment. He traces the development of the notion of "environment" from the medieval idea--which encompasses both human and (...) natural systems--to our modern definition, which separates social systems from the external environment. In Luhmann's thought, human beings form part of the environment, while social systems consist only of communications. Utilizing this distinctive theoretical perspective, Luhmann presents a comprehensive catalog of society's reactions to environmental problems. He investigates the spheres of the economy, law, science, politics, religion, and education to show how these areas relate to environmental issues. Ecological Communication is an important work that critically examines claims central to our society--claims to modernity and rationality. It will be of great importance to scholars and students in sociology, political science, philosophy, anthropology, and law. (shrink)

This work represents Niklas Luhmann's definitive application of systems theory to the understanding of law. In it Luhmann reviews past attempts to create a theory of law and argues they all fail to capture how law operates in modern society. He presents an alternative, critical theory through analysing law as a system of communication.

Massimiliano Tomba’s Insurgent Universality traces a global history of revolutionary institution-building as ‘theory in action’, pushing radical democracy beyond an ontology of the political. This contribution aims to clarify the place of ‘insurgent institutions’ in Tomba’s work and suggests that an unresolved tension persists between insurgent universality as popular institutions on the one hand, and as a negative dis-ordering on the other. Exploring the promise and limitations of ‘insurgent institutions’ in light of their durability, its first part reads Insurgent Universality (...) alongside Santi Romano, the legal pluralist whose concept of the institution Tomba adopts. Secondly, the article turns to Hannah Arendt’s understanding of authority and Miguel Abensour’s discussion of ‘insurgent institutions’ as two potentially helpful accounts of democratic practice within durational time. Where Tomba remains focused on constellations between moments of rupture, Arendt and Abensour offer a politically generative understanding of durability specific to radical-democratic institutions.

This collection of five essays by Germany’s most prominent and influential social thinker both links Luhmann’s social theory to the question “What is modern about modernity?” and shows the origins and context of his theory. In the introductory essay, “Modernity in Contemporary Society,” Luhmann develops the thesis that the modern epistemological situation can be seen as the consequence of a radical change in social macrostructures that he calls “social differentiation,” thereby designating the juxtaposition of and interaction between a growing number (...) of social subsystems without any hierarchical structure. “European Rationality” defines rationality as the capacity to see the difference between systems and their environment as a unity. Luhmann argues that, in a world characterized by contingency, rationality tends to become coextensive with imagination, a view that challenges their classical binary opposition and opens up the possibility of seeing modern rationality as a paradox. In the third essay, “Contingency as Modern Society’s Defining Attribute,” Luhmann develops a further and probably even more important paradox: that the generalization of contingency or cognitive uncertainty is precisely what provides stability within modern societies. In the process, he argues that medieval and early modern theology can be seen as a “preadaptive advance” through which Western thinking prepared itself for the modern epistemological situation. In “Describing the Future,” Luhmann claims that neither the traditional hope of learning from history nor the complementary hope of cognitively anticipating the future can be maintained, and that the classical concept of the future should be replaced by the notion of risk, defined as juxtaposing the expectation of realizing certain projects and the awareness that such projects might fail. The book concludes with “The Ecology of Ignorance,” in which Luhmann outlines prospective research areas “for sponsors who have yet to be identified.”. (shrink)

Das Buch untersucht die Relation der Ahnlichkeit in ihrer Bedeutung fur Asthetik und Epistemologie der Moderne. HAtte Michel Foucault in Die Ordnung der Dinge die These formuliert, dass die Ahnlichkeit ihre Rolle als strukturierende Form des Wissens im Laufe des siebzehnten Jahrhunderts verloren habe, so geht die vorliegende Untersuchung davon aus, dass das Ahnlichkeitsdenken auch in der Moderne von grundlegender Bedeutung ist. LEitend ist dabei die Annahme, dass die Ahnlichkeit ihre besondere Relevanz nun in einem Diskurs uber asthetische Erfahrung entfaltet, (...) wobei sich von dort aus wiederum fundamentale Fragestellungen der Erkenntnistheorie eroffnen. DEn Ausgangspunkt der Untersuchung bildet die Philosophie Immanuel Kants in ihrer maSSgeblichen Bedeutung fur asthetische Theorien der Moderne. ANhand detaillierter Lekturen von Texten von Walter Benjamin, Paul Valéry und Theodor W. ADorno wird die Argumentation weiter entfaltet, womit auch die in der Forschung bislang nicht berucksichtigte Konstellation Valéry - Benjamin - Adorno erstmals genauer in den Blick genommen ist. DIe Arbeit ist im Fach der Literaturwissenschaft angesiedelt, jedoch grundsatzlich interdisziplinar auf Fragen der Asthetik und Kunsttheorie ausgerichtet. (shrink)

Negative externalities pervade immigration law. For example, immigration rules can cause negative economic externalities by barring foreign nationals whose participation would make labor markets more efficient. On the other hand, sweeping executive-branch measures to assist immigrants may unduly expand executive power and yield adverse effects on governance. This essay divides immigration's negative externalities into three categories: economic, relational, and rhetorical. It then argues for specific legal and policy measures, including tailored executive discretion over deportation; more robust court review of immigration (...) restrictions that affect foreign nationals outside the United States; and classifying deportation of lawful permanent residents of the United States as punishment requiring advance notice that specific acts can prompt removal, like the notice the Constitution's Ex Post Facto Clause requires for criminal laws.

We examine the extent to which multiple social identities are associated with enhanced health and well-being in retirement because they provide a basis for giving and receiving social support. Results from a cross-sectional study show that retirees ( N = 171) who had multiple social identities following (but not prior to) retirement report being (a) more satisfied with retirement, (b) in better health, and (c) more satisfied with life in general. Furthermore, mediation analyses revealed an indirect path from multiple social (...) identities to greater satisfaction with retirement and better health through greater provision, but not receipt, of social support to others. These findings are the first to point to the value of multiple group membership post-retirement as a basis for increased opportunities to give meaningful support to others. We discuss the theoretical and practical implications for the management of multiple identities in the process of significant life transitions such as retirement. (shrink)

One of the more powerful recurring motifs in the Iliad is that of the grief-stricken woman lamenting the death of a hero. As with much else in the Homeric epics, these scenes have a formulaic character; when Briseis laments Patroclus, and Hecuba, Andromache and Helen lament Hector, each is depicted delivering a specialized form of speech, specific to the context of a woman's lament. The narrative depiction of grieving women, as well, is formalized, with specific gestures and recurring images that (...) typify these scenes. One element of this depiction that has largely escaped serious consideration is the comparison of a woman in her initial moment of recognition of the corpse to Aphrodite. In this article, I will argue that the allusion is not merely to her beauty but to the myth of Aphrodite and Adonis, specifically the moment of the goddess’ discovery of the death of her mortal lover. As the earliest surviving explicit reference to Adonis in Greek literature appears c.600 b.c.e., this would require a raising of the terminus ante quem for the transmission of the Adonis myth from the Near East to the mid eighth century.

Studying a complex cultural phenomenon like music requires many kinds of expertise. Savage et al. adopt a pluralistic approach, considering multiple forms of evidence and perspectives from multiple fields. This commentary argues that a similar scholarly ecumenicism should be embraced by more studies of music and other cultural phenomena.

In this paper I argue that it’s impossible for there to be a single universal theory of meaning for a language. First, I will consider some minimal expressiveness requirements a language must meet to be able to express semantic claims. Then I will argue that in order to have a single unified theory of meaning, these expressiveness requirements must be satisfied by a language which the semantic theory itself applies to. That is, we would need a language which can express (...) its own meaning. It has been well-known since Tarski that theories of meaning whose central notion is truth can’t be expressed in a language which they apply to. Here, I develop Quine’s formulation of the Liar Paradox in grammatical terms and use this to extend Tarski’s result to all theories of meaning. This general version of the paradox can be formalised as a special case of the Lawvere Fixed-Point Theorem applied to a categorial grammar. Taken together with the initial arguments, I infer that a universal theory of meaning is impossible and conclude the paper with a brief discussion on what alternatives are available. (shrink)

Die Abschiedsvorlesung von Niklas Luhmann an der Universität Bielfeld 1993 unter dem Titel: "Was ist der Fall?" und "Was steckt dahinter?" - Die zwei Soziologien und die Gesellschaftstheorie.

In this volume, Niklas Luhmann, the leading exponent of systems theory, explores its implications for our understanding of law. The volume provides a rigorous application to law of a theory that offers profound insights into the relationships between law and other aspects of contemporary society, including politics, the economy, the media, education, and religion.Readership: Academics and students of sociology, law, philosophy, and legal philosophy.

This chapter brings together Murdoch’s thoughts about language with other central aspects of her thought such as love, attention, perfectionism and morality. By making clear how Murdoch’s variety of linguistic philosophy differs from contemporary philosophy of language, this paper also shows that Murdoch’s philosophy contains the seeds for a fruitful form of philosophizing which brings the moral and aesthetic dimensions of language into view. “Taking the linguistic method seriously” means making clear the ways in which all concepts belong to a (...) fabric that is changing on a personal level as well as an historical one. One of the things that Murdoch can help us see is that one problem with contemporary philosophy of language, is that it does not take the linguistic method seriously enough. (shrink)

The thesis aims at analyzing the concepts of risk and safety as well as the class of concepts to which they belong, thick concepts, focusing in particular on the normative aspects involved. Essay I analyzes thick concepts, i.e. concepts such as cruelty and kindness that seem to combine descriptive and evaluative features. The traditional account, in which thick concepts are analyzed as the conjunction of a factual description and an evaluation, is criticized. Instead, it is argued that the descriptive and (...) evaluative aspects must be understood as a whole. Furthermore, it is argued that the two main worries evoked against non-naturalism – that non-naturalism cannot account for disagreement and that it is not genuinely explanatory – can be met. Essay II investigates the utilization of the Kripke/Putnam causal theory of reference in relation to the Open Question Argument. It is argued that the Open Question Argument suitably interpreted provides prima facie evidence against the claim that moral kinds are natural kinds, and that the causal theory, as interpreted by leading naturalist defenders, actually underscores this conclusion. Essay III utilizes the interpretation of the Open Question Argument argued for in the previous essay in order to argue against naturalistic reduction of risk, i.e. reduction of risk into natural concepts such as probability and harm. Three different normative aspects of risk and safety are put forward – epistemic uncertainty, distributive normativity and border normativity – and it is argued that these normative aspects cannot be reduced to a natural measure. Essay IV provides a conceptual analysis of safety in the context of societal decision-making, and argues for a notion that explicitly includes epistemic uncertainty, the degree to which we are uncertain of our knowledge of the situation at hand. Some formal versions of a comparative safety concept are also proposed. Essay V puts forward a normative critique against a common argument, viz. the claim that the public should follow the experts’ advice in recommending an activity whenever the experts have the best knowledge of the risk involved. The importance of safety in risk acceptance together with considerations from epistemic uncertainty makes the claim incorrect even after including plausible limitations to exclude ‘external’ considerations. Furthermore, it is shown that the scope of the objection covers risk assessment as well as risk management. Essay VI provides a systematized account of safety engineering practices that clarifies their relation to the goal of safety engineering, namely to increase safety. A list of 24 principles referred to in the literature of safety engineering is provided, divided into four major categories. It is argued that important aspects of these methods can be better understood with the help of the distinction between risk and uncertainty, in addition to the common distinction between risk and probability.

“I am, but I do not own myself”—this famous formula of Plessner conceives man as an excentric subject, i.e. a being who can never dominate and dispose of himself as a whole. If we add to Plessner's dictum Bloch's answer to it: “I am. But I do not own myself. Therefore we are still becoming” then we are already suggesting the anthropological space of the imaginary; because the ability to imagine something that is not, plays an essential role in this (...) subject's becoming.

Safety is an important topic for a wide range of disciplines, such as engineering, economics, sociology, psychology, political science and philosophy, and plays a central role in risk analysis and risk management. The aim of this thesis is to develop a concept of safety that is relevant for decision-making, and to elucidate its consequences for risk and safety research and practices. Essay I provides a conceptual analysis of safety in the context of societal decision-making, focusing on some fundamental distinctions and (...) aspects, and argues for a more complex notion than what is commonly given. This concept of safety explicitly includes epistemic uncertainty, the degree to which we are uncertain of our knowledge of the situation at hand. It is discussed the extent to which such a concept may be considered an objective concept, and concluded that it is better seen as an intersubjective concept. Some formal versions of a comparative safety concept are also proposed. Essay II explores some consequences of epistemic uncertainty. It is commonly claimed that the public is irrational in its acceptance of risks. An underlying presumption in such a claim is that the public should follow the experts’ advice in recommending an activity whenever the experts have better knowledge of the risk involved. This position is criticised based on considerations from epistemic uncertainty and the goal of safety. Furthermore, it is shown that the scope of the objection covers the entire field of risk research, risk assessment as well as risk management. Essay III analyses the role of epistemic uncertainty for principles of achieving safety in an engineering context. The aim is to show that to account for common engineering principles we need the understanding of safety that has been argued for in Essays I-II. Several important principles in engineering safety are analysed, and it is argued that we cannot fully account for them on a narrow interpretation of safety as the reduction of risk. An adequate concept of safety must include not only the reduction of risk but also the reduction of uncertainty. (shrink)

The articles included in this thesis centre on what can be called the normative basis of risk analysis. Since risk analyses are decision procedures, they should adhere to norms of rational decision-making, and this they do. Most risk analysis schemes are built on a notion of the decision theoretic maxim that the goal of every decision is to maximize expected utility. However, for some thirty years now this maxim has been called into question. The idea is not that it is (...) unreasonable in itself, but that the theoretical construct of which it is a consequence is in some way inappropriate. Idealizations of the theories are criticized for being too excessive. They do not properly cover cases where the decision maker has poor or, as it were, imprecise knowledge. These are situations where risks are not only about the consequences of the decision but also there are risks with the knowledge itself, epistemic risks. If it is important for a normative decision theory to be not only ideal as a theoretical construct, but to have, in addition, a prescriptive purpose, that theory should also be applicable to actual decision makers and to somehow deal with epistemic risks. The first two papers are about what kinds of decision theory there are, and how best to construe them. The first describes the differences between normative, descriptive and prescriptive decision theories. The second asks whether there is anything intrinsic to the theory that makes it normative or descriptive. Paper 3 asks on what grounds risk assessment is required to be separated from risk management in the risk analysis process. It is argued that the separation is there to ensure that epistemic values are held apart from non-epistemic values. The paper ends by arguing that, in efforts to improve risk management decision-making, it is more important to be explicit about scientific uncertainty than it is to separate sets of values. Paper 4 argues for a more complete decision-theoretic basis for risk analysis. The contrast here is with the bifurcated process of maximizing expected utility when sufficient knowledge is available and using the precautionary principle in cases where knowledge is more limited. Paper 5 investigates the notion of epistemic risk in detail. (shrink)

AimsTo examine attitudes towards physician-assisted suicide (PAS) among physicians in Sweden and compare these with the results from a similar cross-sectional study performed in 2007.ParticipantsA random selection of 250 physicians from each of six specialties (general practice, geriatrics, internal medicine, oncology, surgery and psychiatry) and all 127 palliative care physicians in Sweden were invited to participate in this study.SettingA postal questionnaire commissioned by the Swedish Medical Society in collaboration with Karolinska Institute in Stockholm. ResultsThe total response rate was 59.2%. Slightly (...) fewer than half [47.1% (95% CI 43.7–50.5)] of the respondents from the six specialties accepted PAS, which is significantly more than accepted PAS in the 2007 study [34.9% (95% CI 31.5–38.3)]. Thirty-three percent of respondents were prepared to prescribe the needed drugs. When asked what would happen to the respondent’s own trust in healthcare, a majority [67.1% (95% CI 63.9–70.3)] stated that legalizing PAS would either not influence their own trust in healthcare, or that their trust would increase. This number is an increase compared to the 2007 survey, when just over half [51.9% (95% CI 48.0–55.2)] indicated that their own trust would either not be influenced, or would increase.ConclusionsThe study reveals a shift towards a more accepting attitude concerning PAS among physicians in Sweden. Only a minority of the respondents stated that they were against PAS, and a considerable proportion reported being prepared to prescribe the needed drugs for patient self-administration if PAS were legalized.

This article is about the justifiability of accepting worse cost effectiveness for orphan drugs, that is, treatments for rare diseases, in a publicly financed health care system. Recently, three arguments have been presented that may be used in favour of exceptionally advantageous economic terms for orphan drugs. These arguments share the common feature of all referring to considerations of justice or fairness: the argument of the irrelevance of group size, the argument from the principle of need, and the argument of (...) identifiability. It is argued that all of these arguments fail to support the conclusion that orphan drugs should be subsidized to a larger extent than treatments for common diseases. The argument of the irrelevance fails to distinguish between directly and indirectly relevant considerations of fairness or justice. The recent attempt to revive the moral relevance of identifiability has provided no novel reasons to think that identifiability is morally relevant in itself or due to considerations of fairness and justice. The argument from the principle of need does not fail due to any inherent flaw in the principle as such. Rather, this principle can be interpreted in different ways, and none of these interpretations support exceptionally advantageous terms economically for treating rare diseases specifically. It is concluded that we are awaiting justice based reasons for the preferential treatment of orphan drugs. (shrink)

Language Lost and Found takes as its starting-point Iris Murdoch's claim that "we have suffered a general loss of concepts." By means of a thorough reading of Iris Murdoch's philosophy in the light of this difficulty, it offers a detailed examination of the problem of linguistic community and the roots of the thought that some philosophical problems arise due to our having lost the sense of our own language. But it is also a call for a radical reconsideration of how (...) philosophy and literature relate to each other on a general level and in Murdoch's authorship in particular. (shrink)
